Homeland Security teacher David Mains instructs classes at LBCC with discussions of past events, current events and what is possible in the future.
The classes cover legalities, politics and impacts of how the nation is protected and the various agencies involved.
Mains said, “We invite guest speakers or subject matter experts to come in and talk about specific issues.”
Mains said in an email his background includes 30 years of law enforcement as a sworn officer, with an emphasis in Homeland Security since the terrorist attacks Sept. 11, 2001.
He is a trained terrorism liaison officer and works a Homeland Security maritime detail.
“Based on my background and experience, I am able to offer my students a real-world perspective.”
The Port of Long Beach hosts free boat tours to educate the public. The 90-minute narrated tours are conducted every Summer.
Mains said, “We have a great relationship with the port and they have been great in offering these tours to our students.
“When my students attend, they receive extra credit.
“I recommend the tour to my students so that they may see firsthand the daunting reality of securing a port the size of Long Beach and the way security is conducted on a layered basis.”
Chris Oropeza, 21, a Homeland Security major, said, “If you’re looking to be certified and more educated on current threats, this is the class to take.”
The Our Homeland Security Club sponsored the event, but opened it up to other LBCC students who wished to attend.
